To @ZZ whom 25 may concern:

Be it known that I, OHARLEsJ.' I-IoRGEN, a citizen of the United States,and a resident of the city of New York, borough of Brooklyn,

in the county of Kings and State 'of New- York, have invented va new andIm roved Hoisting and Conveying Apparatus, o which thefollowing isafull, clear, and exact' description.

My invention relates to a device for hoist-l ing and conveying `purposesin general, and is the upper side of theblock, and is providedespecially applicable `.to loading andunload-y ing ships. p p

The invention comprises a cable or'similar` flexible elementplacedonanineline and af carriage mounted on the cable and adaptedy to movealong it, the carriage being provided with automatic means for.manipulating. a

pulleyto assist in the several operationsv of' 2o loading and unloading.

Fig. 1 shows a wharf provided'wth av block? 10, connected with astationary support in: any desired mannery and having a cableor` (otherflexible element 11 secured thereto,

This cable passes' upwardly at an angle of about twenty degrees to ablock 12 and through the same to a windlass13 on ther boat. The block 12is preferably connected with the mast of theboat by means of two y shortcables 14, constituting a triangle, and a halyard 14a from the masthead,hooked to with pulleys15 (shown in dotted lines in Fig. 4)`-forguidingthe cable 11, Riding on the cable 11 is a carriage 16, to whichissecured the end of acable 17. This c'ablepasses under a-.pnlley 18,which is vertically movable 'with respect to the carriage and isdesigned Y to carry aloadfv The cable 17 then passes:

Figure 1 is a perspective view showing af `boat iitted up with anapparatus embodying the principles of :I ny'invention. Fig.` 2 is afyside elevation, partly in section, of a block? constituting v.an anchorfor the lower end of? and Fig. 5 isa- Patented March 2o,19o6.

lthroughthe carriage'tov the block 12 and from there down to ahoisting-engine 21 on the boat. The block 12 is provided with a pulley22 for guiding the cable and the carriage with a pulley 23 for thesame'pur'pose.

The carriage is mounted'on wheels 24, runningon the cable 11. 1 Eachofthe'blocks has 4a buffer 25 for yieldingly resisting the jar of i thecarriage when it strikesit. provided vfor automatically locking thecar-V riage to each blockwhen it strikes. For this purpose the block 1 0is constructed with a cavity 26, having a pin 27, passing transverselyacross`it. L

On the" carriage is located apivoted lever y 28, having acatch 29',adapted tov engage `the Y pin'27 when broughtinto proper position. A

spring 30 normally holdsv the hook in proper position for engagingthepin'.y l Av 'pin 31 isl employed on the carriage tollmit the movement ofthe lever vin one' direction. The other block is provided with a cavity32, having'a pin 33, and on the carriage is mounted a s ec-- l 'ondlever' 34, having a catch 35 for engaging the last-'named pin.- In,order to operate Meansare also these levers to automatically unlock themat the* proper times andA to support the load `while thecarriage ismoving along the cable *11, the vfollowing mechanism 1s provided:Transversely'across the carriage extends a shaft 36. On the outsideofthe carriage two bars 37 are placed, each bar having an elongatedslotthrough which they are pivoted on the shaft 36. VThis permits avertical motion as well as a swing motion Each of the bars. is

providedwith a 'channel 39 upon its inner surface. This'channel isformed4 with three camp-surfaces 40, 41, and 42, the latter beinglocated at the top of an extension 43, which 1s provided with two othercam-surfaces44 and 45 on'the right andsleft hand side thereof. Thecarriage having a vertical slot 46 adjacent to the position occupied bythe channel 39 vwhen it is in normal position, a pair of studsy .I 47 ona frame 48, which supports the pulley 18, isfree to move upwardly intothechannel 39. This arrangement is provided so 'that the pulley 18 andthe weight supported there- IOO by can becarrieddirectly by the carriagethrough the instrumentalityof the cam-surface 42, on which the stud 47is adapted to rest. The carriage is also formed'with aslot les 49forreceiving a lstud "50, mountedon ay pro'- jection 51 on the arm 37.This stud engages a reciprocating bar 52 and is operated by it. This barhas an elongated slot 52a, in which operates a stud 53, mounted in astationary position on the carriage.

At the upper end the arms 37 are provided with a transverse pin 54,which passes through a slot 55 in the lever 34. This slot is formed Withtwo depressions 56, large enough to receive the pin 54. A spring 57normally holds the lever 34 in the proper position for keeping the catch35 low enough to engage the pin 33- when the carriage moves against theblock 12. The block 12 is provided with a nose or projection 58, theupper surface 59 of which is curved and inclined for a purpose whichWill be stated below.

Springs 60 are employed to suspend the bars 37 and keep them in centralposition, but permit them to yield. These springs are connected with thepins 61, which can reciprocate in slots 62 in the carriage 16.

The operation of the device will now be described. Assuming the studv 47to be in the channel 39 and resting on the surface 42, as shown indotted lines in Fig. 3, and that the cable 17 is being let out, so thatthe carriage slides down the inclined cable 11, it will be seen thatwhen the carriage engages the buffer 25 the end of the bar 52 willengage the outer surface of the block 10. This pushes the bar rearwardlywith respect to the carriage and swings the arms 37 about the shaft 36,so that the surface 42 will move out of the way of the stud 47. Thisremoves the support of the latter and it drops out. The weight of thepulley 18 now causes it to descend, taking with it the cable 17, whichis being paid out at the other end under control of the brake. Thedescent of the pulley to the desired place will be readily understood.In an obvious manner the catch 29 engages the pin27 when the carriagereaches the position described above, and also when the bar 52 is pushedinwardly the pin 54 engages the left-hand slot 56. This holds the arms37 in the position in which they were forced by the bar 51. As the arms37 are normally held in an elevated position by springs 60, the ascentof the pulley 18 when the hoisting-engine is operated to raise it willcause the studs 47 to slide up the Ycam-surface 45 and engage thecam-surface 41 .whi ch at that time is in registration with the slot 46.Further force applied by the hoisting-engine will operate to cause thestuds to engage the bar 28, which is located behind the slot 46, anddisengage the catch 29 from the pin 27. This allows the carriage to moveupwardly along the cable, and when this operation commences the studs 47will settle .back onto the cam-surface 42 and this will pull the arms 37into their lowermost position, .bringing them also back to centralposition, with the pin 54 between the two slots 56.

When the carriage reaches the block 12, the catch 35 is at iirst in sucha position that it cannot engage the pin 33 on account of the weight onthe arms 37 g but the continued operation of pulling on the cable 17forces the studs 47 to rise against the cam-surface 4() and then to dropalong the cam-surface 44 and force the arms to the rear, so that the pin54 will engage the right-hand depression 56 and the pulley will slideoif from its support. The engine is stopped at this time and the weightlowered to the deck by the ordinary means, it being controlled as usual,by a brake or the like. Before this occurs the carriage is forced up theincline 59, so that it is left in a position with its front lowersurface on the inclined surface 59, and as soon as the Weight is removedfrom the surface 42 the spring 57 is free to act to force the catch intoengagement with the pin 33, so as to lock the carriage to the block. Inraising the load and pulley to the block again theiirst operation is tocause the studs 47 to engage the surface 41 and drop back against thesurface 42 when the strain on the cable caused by the hoisting-engine isremoved. As the carriage is held up by the surface 59 until this time,it will be seen that the weight of the pulley and load thereon will freethe catch 35 from the pin 33 and allow the carriage to slide down thisincline and then run down the inclined cable. From this point theoperations described above can be repeated.

Among the advantages of theinvention are the fact that the carriage runson a cable which can be adjusted from the boat to suit thecircumstances, and a single operating-cable is used to operate thecarriage, all changes of direction and motion from vertical to inclinedbeing effected automatically by the mechanism described.
